Ruby-throated Hummingbirds are bright emerald or golden-green on the back and crown, with gray-white underparts. Males have a brilliant iridescent red throat that looks dark when it’s not in good light.

Ruby-throated Hummingbirds fly straight and fast but can stop instantly, hover, and adjust their position up, down, or backwards with exquisite control. They often visit hummingbird feeders and tube-shaped flowers and defend these food sources against others. You may also see them plucking tiny insects from the air or from spider webs.
